A biology class in Jamaica studied human reproduction. A student correctly stated that the acrosome of the sperm cell contains enzymes. What is the function of these enzymes during fertilisation?

Q: How do I try a free CXC Biology question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Biology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Biology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Biology questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Biology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A biology class in Jamaica studied human reproduction. A student correctly stated that the acrosome of the sperm cell contains enzymes. What is the function of these enzymes during fertilisation?

Accepted Answer

To digest the outer membrane of the egg cell to allow penetration — Award 1 mark for correctly identifying the role of acrosomal enzymes in penetrating the egg membrane. A is incorrect because energy is provided by mitochondria in the mid-piece of the sperm. C is incorrect because seminal fluid helps neutralise acidic conditions, not acrosomal enzymes. D is incorrect because hormones (LH) trigger ovulation, not sperm enzymes.

Answer

To digest the outer membrane of the egg cell to allow penetration

Answer

To provide energy for the sperm to swim

Answer

To neutralise the acidic environment of the vagina

Answer

To trigger the release of the egg from the ovary
